menuconfig ETH_NATIVE_POSIX
bool "Native Posix Ethernet driver"
depends on ARCH_POSIX
help
Enable native posix ethernet driver. Note, this driver is run inside
a process in your host system.
if ETH_NATIVE_POSIX
config ETH_NATIVE_POSIX_STARTUP_AUTOMATIC
bool "Start network interface automatically"
help
If set, the native_posix ethernet driver will set up the network
interface, requiring ``zephyr.exe`` to be run with root privileges
(needed to create and configure the TAP device).
If not set (the default and recommended way), the network interface
must be set up manually using ``net-setup.sh`` (from the net-tools
project repo). The ``zephyr.exe`` program can then be run as a
non-root user.
if ETH_NATIVE_POSIX_STARTUP_AUTOMATIC
config ETH_NATIVE_POSIX_SETUP_SCRIPT
string "Host setup script"
default "${ZEPHYR_BASE}/samples/net/eth_native_posix/net_setup_host"
help
This option sets the name of the script that is run when the host TAP
network interface is created. The script should setup IP addresses
etc. for the host TAP network interface.
The default script accepts following options:
-i|--interface <network interface name>, default is zeth
-f|--file <config file name>, default is net_setup_host.conf
If needed, you can add these options to this script name option.
Note that the driver will add -i option with the value of
CONFIG_ETH_NATIVE_POSIX_DRV_NAME option to the end of the options
list when calling the host setup script.
config ETH_NATIVE_POSIX_STARTUP_SCRIPT
string "Host startup script"
default ""
help
This option sets the name of the script that is run when the host TAP
network interface is created and setup script has been run.
The startup script could launch e.g., wireshark to capture
the network traffic for the freshly started network interface.
Note that the network interface name CONFIG_ETH_NATIVE_POSIX_DRV_NAME
is appended at the end of this startup script name.
Example script for starting wireshark is provided in
${ZEPHYR_BASE}/samples/net/eth_native_posix/net_start_wireshark.sh
file.
config ETH_NATIVE_POSIX_STARTUP_SCRIPT_USER
string "Username to run the host startup script"
default ""
help
By default the startup script is run as a root user. Set here the
username to run the script if running it as a root user is not
desired. Note that this setting is only for startup script and not
for the setup script. The setup script needs to be run always as
a root user.

config ETH_NATIVE_POSIX_DRV_NAME
string "Ethernet driver name"
default "zeth"
help
This option sets the driver name and name of the network interface
in your host system.
config ETH_NATIVE_POSIX_DEV_NAME
string "Host ethernet TUN/TAP device name"
default "/dev/net/tun"
help
This option sets the TUN/TAP device name in your host system.
config ETH_NATIVE_POSIX_PTP_CLOCK
bool "PTP clock driver support"
default y if NET_GPTP
select PTP_CLOCK
depends on NET_GPTP
help
Enable PTP clock support.
config ETH_NATIVE_POSIX_RANDOM_MAC
bool "Random MAC address"
depends on ENTROPY_GENERATOR
default y
help
Generate a random MAC address dynamically.
config ETH_NATIVE_POSIX_VLAN_TAG_STRIP
bool "Strip VLAN tag from Rx frames"
depends on NET_VLAN
help
Native posix ethernet driver will strip of VLAN tag from
Rx Ethernet frames and sets tag information in net packet
metadata.
if ! ETH_NATIVE_POSIX_RANDOM_MAC
config ETH_NATIVE_POSIX_MAC_ADDR
string "MAC address for the interface"
default ""
help
Specify a MAC address for the ethernet interface in the form of
six hex 8-bit chars separated by colons (e.g.:
aa:33:cc:22:e2:c0). The default is an empty string, which
means the code will make 00:00:5E:00:53:XX, where XX will be
random.
